Hello list,
I wrote about this to the X.org mailing list some time ago, but noone
answered, so I hope you don't mind that I try here.
My posting to the X.org mailing list can be found here:
http://lists.freedesktop.org/archives/xorg/2006-October/018679.html
I get the following warnings once my X server starts:
mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000
mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000
mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000
mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000
mtrr: 0xd0000000,0x10000000 overlaps existing 0xd0000000,0x8000000
In Xorg.0.log I get these warnings:
(WW) RADEON(0): DRI init changed memory map, adjusting ...
(WW) RADEON(0): MC_FB_LOCATION was: 0xd7ffd000 is: 0xd7ffd000

(**) RADEON(0): GRPH_BUFFER_CNTL from 20205c5c to 203e5c5c
/proc/mtrr holds these values:
reg00: base=0x00000000 ( 0MB), size= 512MB: write-back, count=1
reg01: base=0xe0000000 (3584MB), size= 32MB: write-combining, count=2
reg02: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=1
Could all this relate to lspci showing the wrong amount of RAM available
on my graphics card?

It shows 256MB, but I only have 128MB. Is there a bug in the kernel that
messes up getting the memory amount?
I'm using 2.6.18 vanilla, a Sempron 32bit cpu (2400+), a nforce2
mainboard and a Radeon 9250 graphics card.

Same here:

mtrr: 0xd0000000,0x8000000 overlaps existing 0xd0000000,0x4000000
